Make no mistake, the Food Conglomerates are scared s-less, now that the truth is coming out about Carbs and Intermittent Fasting.
A few months ago I did a five day fast. After the first two days it was easy peasy. You do have to take some mineral supplements, though. I was going for 30 days but my wife was out of town and she threatened to come back early if I didn’t eat. She was afraid she’d come back to a skeleton stripped bare and a well fed Maltipoo.
